基于“IPv6+”的应用感知网络(APN6)

Application-aware IPv6 networking

互联网应用对网络带宽、时延、抖动、分组丢失率等方面的需求各不相同,而网络和应用的解耦导致网络无法有效感知应用的需求,因此难以为应用提供相应的服务质量SLA保障。提出一个基于IPv6的应用感知网络框架——APN6,通过将应用的需求信息封装在数据分组中,使网络能感知应用及其需求,便于网络进行流量调度和资源调整。设计了一种安全接入控制方案以解决APN6接入场景中存在的应用信息的伪造与篡改问题,确保APN6只对合法用户提供相应服务。

Internet applications have different needs for network bandwidth,latency,jitter,and packet loss.However,the fact that the network and applications are decoupled makes it difficult for the network to be aware of an application’s requirements and ensure its quality of service(e.g.,service level agreement,SLA).A framework called application-aware IPv6 networking(APN6)was proposed,which could encapsulate applications’requirements into packets.Networks could be aware of an application’s requirements and perform traffic steering and network resource adjustment.Besides,a secure access control mechanism was designed to solve application information forgery and tampering issues in APN6,which ensured that APN6 only provided services to legal users.
